The following example below shows a typical property incorporating the sugges-
ted positions for the Control Panel, PIR and Magnetic Detectors for optimum 
security. Use this as a guide for your installation in conjunction with the recom-
mendations contained in this manual for planning your intruder alarm system.

Before attempting to install your Alarm System it is important to study your 
security requirements and plan your installation.

The alarm system may be extended to provide even greater protection by fitting 
additional PIR Detectors and Magnetic Contact Detectors as required.

REMOTE SYSTEM CONTROL
If the Remote System Control facility is enabled, the Control Panel will answer 
the call after the set number of rings and emit three beeps on the phone line to 
prompt for a User Password to be entered using the telephone keypad.

A valid User Password will be acknowledged with one long beep. An incorrect 
code will be acknowledged by two short beeps.

If the User Password is not entered within 30s or is entered incorrectly three 
times then the Control Panel will automatically hang-up the line.

By pressing the        button on the telephone keypad within 30 seconds, the 
Control Panel will automatically hang-up the line.

Use with an External Answer-Phone:
If the Remote System Control is to be used in conjunction with an external 
Answer-Phone then

The number of ‘one call ring’ for the Control Panel must be greater than that of 
the External Answer-Phone, otherwise the Control Panel will always pickup the 
call before the Answer-Phone.

To access the Remote System Control facility the Control Panel has a ‘double call 
dial-in’ feature to enable the Control Panel to pick-up the phone call before the 
external Answer-Phone cuts in.  The ‘double call dial-in’ procedure is as follows:

1. Dial up the system and hang up after two rings.
2. Redial up the system within 28s as maximum (14s as minimum), the system 

will pickup the phone after 1 ring.

3. Enter the User Password as normal.

The following functions may be access via the remote. The system will 
acknowledge each signal with a single long beep.
